The gnulib will set AC_GNU_SOURCE equivivelant if necessary. The awk is
relevant only for contrib stuff, and compiler program was something I had
not understood quite right some years ago when I added it.

I have no idea why that was there. My guess is that I had no idea at the
time I added the line what it does.

Making dhcpd.conf and dhcpd.leases file references being dynamic causes
manual contents being replaced at compile time, so make some other data
items dynamic as well.

Add gnulib modules which make sense and remove few. The stuff gnulib
takes care can be dropped from configure.am.

This will mean better portability, and a good reason to get rid of
various portability autotools directives which where part of this
project.

The problem is, that you simply count all lease occurrences in
dhcpd.leases, but only the last ones for each ip address are
valid. The lease file is more like a logfile of what has been
done, than a real database. To fix the counting issue, I'm using
a single hash (from uthash.h [1]) for the counting. This way
only the last lease entry for each IP gets into my counting
structure.
When you remove the duplicates in prepare_data(), you don't have
the information anymore, if the active lease entry or the free
lease entry came last. Simply deleting each ip from the touches
array, that is already in the leases array, gives you a big
chance to count wrong. Another way of fixing this would be to
not only store the ips in your arrays, but a structure containing
the ip and a global lease entry counter. Then you could delete
all entries except for the latest.

The eprintf removed and replaced with err & warn. Option parsing
no longer tries to find missing optargs, which are getopts should
notice. Few complier warnings got to be removed as well. Finally
the commments will no longer exceed standard terminal width.
